Unrecognized option '--environment' when using dotnet cli tools

[FunkyLambda]

As per the following comment by @bricelam:
#7353 (comment)

I ran this:
dotnet ef database update --startup-project ../<my_project> --environment Development

This gives:
Unrecognized option '--environment'

I'm using:
.NET Command Line Tools (2.1.504)

The --environment options was removed in version 2.0. Use this instead:

set ASPNETCORE_ENVIRONMENT=Development
dotnet ef database update --startup-project ../<my_project>

@bricelam Can I read this value from my migration file (i.e. Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"))? Will it be passed as an env variable?

[bricelam]

@MarounMaroun Yes, that should work.
